Version 2.6.1-signed
Released August 19, 2011
230.4 kB
Works with
Firefox 3.5 and later, SeaMonkey 2.0a and later

New features and changes in v2.6- Added several new surrogate scripts that will be used when an original payload is blocked -- this should resolve issues with sites that appear not to work. Now providing dummy scripts for Google Analytics, Yahoo Web Analytics, Comscore, ShareThis, AddThis, Facebook Connect, Webtrends, and Omniture- Added company affiliations and affiliation filtering to options- Fixed issues with cookie monster throwing errors- Purple box now only loads in the tab the user is looking over- Whitelisting has been changed to allow Ghostery to run detection but skip blocking on a whitelisted page

Bug fixes in v2.5.3- Added Firefox 4 customized button that could be dragged into any of the available toolbars.- Fixed opening Ghostery Options page from Addon Manager.- The number counts in all places (toolbar, options page, and update pages) is now based on the same number -- number of tracked applications.- Applied same auto-update behavior to cookie lists as the bug lists -- if everything is selected for blocking, all new cookies will be blocked as well.- Added upgrade migration script for 2.4+ upgrade to 2.5.3.- Uninstall of Ghostery will now remove Ghostery folder artifacts from profile directory (unless user.db file had data).

Bug fixes in v2.5.2- Blocking layer is now optimized to use simple string matching instead of regex when possible resulting in a faster blocking operation. This resolves issues with script not responding on larger pages.- Re-introduced the Performance Options. While everything is on by default, user has ability to turn some of the more advanced features off speeding up Ghostery.- Upgrade script from 2.4 branch to v2.5 for selected trackers.- UI updates.

Bug fixes in v2.5.1- Translation layer added in Ghostery v2.5 has caused some visual errors in the new options and blocking pages. This issue has been solved.

New features and changes in v2.5- Added cookie protection that looks for cookie transactions (add & edit) and then compares it to the LSO domain list. If a protected LSO is encountered, Ghostery will deny any change and remove the cookie. This is added through a new "experimental" cookie protection checkbox in Ghostery Options. Denied cookies are listed in the block log.- Options and blocking pages have been updated to use HTML instead of Firefox UI components (XUL) -- this gives us a more consistent look and feel across Firefox, Safari and Chrome. Additionally, this resolves the issue with displays being too small to see Save and Cancel buttons in Options.- Added redirection tracking and blocking. This resolves some of the trackers from slipping in when a page issues a 3XX redirect.- Added support for examining Flash (and other) sub-object requests. This allows the requests blocked but not found in DOM to be correctly reported.- Whitelisting has been improved to include any potential frames of a whitelisted parent site. Relaxed whitelisting to be less strict: for example, whitelisting ghostery.com will be applied to www.ghostery.com and apps.ghostery.com.- Groundwork is laid in for user created/maintained tracker lists. This functionality is included in v2.5 branch, tho the UI hasn't been implemented yet.

Bug fixes in v2.4.2- Whitelisting for HTTPS (secure HTTP) sites has been fixed.

New Features in v2.3- Japanese language translation (thanks pul);- Configuration wizard to help introduce users to options that might not be familiar;- Update to blocking behavior - if all bugs are selected to be blocked, then new bugs added in remote updates are blocked by default as well;- Private-browsing mode update - the blocking log and GhostRank are now disabled if Firefox is in private browsing mode;

Improvements and bug fixes in v2.3.1:- Ghostery initial walk-through only opens a single window;- Initial walk-through is only shown for people with brand new Ghostery installation;

New Features in v2.2:- Web site whitelisting - gives a domain a free pass to let trackers run in cases where you trust the publisher, want to support their research, or have concerns about Ghostery affecting functionality;- The Block Log - if you've got blocking enabled, Ghostery may actually be busier than you think - it's occasionally difficult to report back into the friendly purple box all of the scripts that Ghostery kept from running. The "block log" keeps a record of everything Ghostery blocks (across all the tabs you have open) so you can check out Ghostery's activity in all of its busybody glory. It's available in the Tools -> Ghostery menu;- Performance options panel with GhosteryLite mode - turns off some detection and extra goodies in favor of performance. You won't notice or block as many trackers, but for users looking for ultra-quick performance will see a 15% faster Ghostery over full featured mode (a full 23% faster over previous versions);- Tab switching is now disconnected from page scanning;- Look and Feel option panel - allows for purple alert to be re-positioned;- Fixed a couple of detection scripts to eliminate some troublesome false positives (blocking Facebook Connect no longer keeps Facebook from operating, etc);

Note on whitelisting:Adding sample-site.com to the whitelist will not automatically make sub-domains of sample-site.com whitelisted. So, if you have added sample-site.com to whitelist, but you are browsing www.sample-site.com, Ghostery will assume that www.sample-site.com is not in the whitelist and will execute on the site until you add www.sample-site.com to the whitelist as well.
